No, 13 is not generally considered too late for a girl to get her first period.
Girls typically begin menstruation (getting their first period) between the ages of 8 and 15, about 2 to 2½ years after the first signs of puberty appear. These signs often include breast development, or sometimes pubic hair. So, at age 13, a girl is still within the typical age range to begin menstruating.
| Age | Likelihood of Period |
|---|---|
| 8 - 15 | Typical Range |
| Under 8 | Early, see a doctor |
| Over 15 | Delayed, see a doctor |
If a girl hasn't started her period by age 15, it is recommended that she see a doctor to investigate any possible underlying causes for the delay.
